I'm wondering if anyone on here has updated their <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a> only to find it predict your next period way off, even when it's been consistent in the log for months. I took ovulation tests, & when I logged my positives, it moved my period due date up 4 days early instead of when it's actually due like clock work. Anyone else have this issue? It's almost disheartening to go so long before you can take a test but it's like a fake missed period since the dates are wrong.
